在bitbake配方中，我的 shell任务需要将http_proxy导出到它调用的进程。 http_proxy已在BB_ENV_EXTRAWHITE列入白名单，因此从bitbake开始${http_proxy}的shell中导出的值在export http_proxy = ${http_proxy}
my_process
中可用。
要将其导出到子任务，我正在执行
File "/usr/lib/python2.7/dist-packages/gunicorn/arbiter.py", line 515, in spawn_worker
worker.init_process()
File "/usr/lib/python2.7/dist-packages/gunicorn/workers/base.py", line 122, in init_process
self.load_wsgi()
File "/usr/lib/python2.7/dist-packages/gunicorn/workers/base.py", line 130, in load_wsgi
self.wsgi = self.app.wsgi()
File "/usr/lib/python2.7/dist-packages/gunicorn/app/base.py", line 67, in wsgi
self.callable = self.load()
File "/usr/lib/python2.7/dist-packages/gunicorn/app/wsgiapp.py", line 65, in load
return self.load_wsgiapp()
File "/usr/lib/python2.7/dist-packages/gunicorn/app/wsgiapp.py", line 52, in load_wsgiapp
return util.import_app(self.app_uri)
File "/usr/lib/python2.7/dist-packages/gunicorn/util.py", line 366, in import_app
import(module)
ImportError: No module named travel_buddy.wsgi
这样可行，但给我留下了冗余语法的感觉。这是将父环境变量传递给bitbake任务的正确方法吗？
答案 0 :(得分：2)
我认为这是在bitbake任务中从环境访问变量的正确方法，请参阅http://www.yoctoproject.org/docs/2.4.1/bitbake-user-manual/bitbake-user-manual.html#exporting-variables-to-the-environment。并且（在我看来） Bitbake 旨在与用户环境隔离，而冗余语法是归档此功能的代价。
